9 Claims.

This invention relates to pipes, and has for an object to provide a pipe having improved means for providing elongated passages through the stem from the bowl to the mouthpiece.

A further object of the invention is to provide a pipe having a bowl and mouthpiece with interconnecting stem and passageways through the stem returning `upon themselves to form ducts from the bowl to the mouthpiece several times longer than the stem.

A further object of the invention is to provide a pipe having a bowl and mouthpiece with interconnecting stem with a plurality of chambers located between the bowl and the mouthpiece with the stem provided with a conduit communicating at intervalsV in its extent with the several chambers.

A furher object of the invention is to provide a pipe having a stem formed at one end as a ring With a bowl inserted into the ring from one side, a cap inserted into the ring from the opposite side, said cap and bowlfbeing interconnected by screw threads which lform the sole means for clamping the bowl to the lstem and together clamp the ring rmly between thecap and the bowl.

A further object of the invention is to provide a pipe having a stem with a iiuted filler therein, the 'grooves of said ilutingrforming with the stem a plurality of smoke passages which communicate respectively with a plurality of chambers within the stern, and after traversing the length of the stem a number of times communicate directly with a mouthpiece carried by the stem.

A further object of the invention is to provide a pipe having a stem otherwise hollow-but lled Ywith a ller having corrugations running longitudinally thereof, each coacting with the interior walls of the stem for smoke passages, one of which is in communication with a chamber underlying the bowl, another in communication with two chambers spaced at opposite-ends of the stem with a third passage through said ller com'- munica'ting directly with the mouthpiece.

The invention, therefore, comprises a hollow stem which is provided with a ller having longitudinal corrugations and a longitudinal bore, the hollow stem providing chambers at opposite ends of the ller, one chamber being in communication with one of the grooves. and with the bore, the other chamber communicating with a. conduit which in turn communicates with the chamber underlying the bowl into which chamber a communicating passage from the bowl also opens.

one embodiment `o1! the V20 about the opposite sides.

(Cl. ISI-12) pipe taken in longitudinal section substantially diametrical of the bowl and stem,

Figure 2 is a sectional view taken on line 2-2 of Figure 1,

Figure 3 is a longitudinal sectional view of a 60 modification taken diametrically of the stem and bowl,

Figure 4 is a sectional view taken on line 4-4 of Figure 3, and

Figures 5 and 6 are respectively transverse 65 sectional views taken on lines 5-5 and 6--6 of Figures 1 and 3.

Like characters of reference indicate corresponding parts throughout the several views.

The improved pipe, which forms the subject- 'l0 mattei' of this application, is` shown in the drawing in two embodiments diiering slightly in the matter Vof bowl attachment. In both, stems 10 are made hollow with a ller 11 inserted into the hollow sleeve. This filler 1l has grooves 12 and 75 13 running longitudinally thereof and formed in the otherwise cylindrical surface of the filler.

At Figure 1, the groove l1 terminates slightly short of the end and communicates with an inclined passage 14, while at Figure 3 the ter- 80 mination is nearer the end and terminates at inclined passage 15.

The filler 11 is also provided with an axial bore 16 enlarged at one end to receive the tube 17 carried by the mouthpiece 18. In the type shown at Figure l, the stem is formed as a ring 19, and preferably, though not necessarily, with rabbets The bowl 21 is provided with a neck 22 which extends down inside of the ring 19 and with a groove 23 which 90 coacts with the rabbet 20.

A cap 24. is provided with a groove 25 coacting V with the rabbet 20 on the opposite side of the' ring. The cap is also provided with a sleeve 26, which fits snugly Within the ring, and is provided internally with screw threads which inter-engage with similar screw threads on the neck 22, so `that the bowl 21 is held in airand smoke-tight relation to the ring by merely rotating the cap 24 toY exert tension upon the neck 22.

The bowl is providedwith a passage 27, and preferably, though not necessarily with a tube 28 which extends down into a chamber 29 underlying the neck 22. One side of the neck 22 is provided with a longitudinal passagev30, which 105 forms communication between the chamber 29 and they passage 14 in the stem. The sleeve 26 of the cap 24 is made lsomewhat shorter than the width of the ring 19, so that a passage is provided entirely around the neck 23 above the 110 end of the cap 24, which passage communicates with the conduit 14, so that no matter how the bowl may be arranged rotatably relative to the ring 19, the passage 14 will always communicate through the chamber and through the passage 30 with the chamber 29.

As shown at Figure 3, the bowl 31 is connected directly by screw threads with the chamber 32, such screw threads being shown at 33. As in the case shown at Figure 1, the bowl is provided with the passage 27 and tube 28, which communicates with the chamber 32. A passage 30 is also provided in the neck 22 here shown, and a passage is formed entirely about said bowl in coinmunication with the passage 15 of the stern. In the embodiment shown at Figure 1, the mouthpiece 18 is shown as connecting with the stem by screw threads, and at Figure 3, the connection is shown the same, both being shown at 34. Instead, however, of the connection and disconnection of the bowl from the stem as shown at Figure 1, in Figure V3, the connection isat the slip-joint35 vwith the ller 1lY screw threaded at 36 to receive a short stem part 37 carried integrally bythe member including the chamber 32. t Y v As arranged at Figure 1, in addition to the chamber 29, chambers 38 and 39 are provided. At

'igure 3, the chamber 39 is substantially identical, but the chamber 38, differs slightly in that there isa communicating passage at 40 from the stem section 37 to the chamber 32, which is iilled by the end 41 of the iiller. Ifhe central bore 16 of the ller shownat Figure 3 is also provided with Vlateral openings 42 which communicate with this chamber 38.

In operation, in the type shown at Figure 1,

smoke will pass fromv the bowl 21 through the passage 27 and tube 28A to the chamber 29, then upwardly through the passage 30 to the passage 14 to the chamber 39, through the passage 13 to the chamber 38, through` the central bore 16 and tube 17 to the mouthpiece 18. In the type shown at Figure 3, the smoke will pass through the bowl 31, through the passage 27 and tube 28 to the chamber 32, then through the passages 30 vand 15, through the chamber 39, through the passage 13 to the chamber 28, through the lateral openings 42 to the bore 16 of the filler, and through the tube 17 of the mouthpiece. In its travel, the smoke will, therefore, pass through passages substantially three times the length of the stem, and will, therefore, be subjected to cooling influences the equivalent of the stem nearly three times asV long. It will also pass through the three chambers 29, 38 and 39, each of which chambers isreadily accessible.

In the type shown at Figure 1, the removal of the mouthpiece 18 will make thechamber 39 accessible. VBy the removal ofthe cap 24, the

bowl andcap maybe removed from the ring 19, andthe Vchamber 29 opening off from the capvvwill be easily accessible as will also be the chamber 38 and passage 14. Y

In the type shown at Figure 3, the mouthpiece is similarly removed, but the stem is disconnected at the slip-joint 35 by the use ofthe threads 36. The removal of the bowl in this manner will remove kthe ller 11 from the chamber 38 and will also open the-passage 40 between the chambers 38 and 32, whereby both of these chambers are accessible for cleaning.
